720p50 and 720p60 HDV Tape-Based Device Support:

In Final Cut Pro 6.0.2, you can now capture from and output to JVC 720p50 and 720p60 HDV tape-based devices.


50p Support

I checked before I posted. But I missed this. Sorry for the double post. The good thing is after a year -- or was it longer -- we have full support.

Now if only Avid would support ProHD. :)
